Laptops linked to male infertility

MAYWOOD, Ill., June 15 (UPI) -- Men who aspire to fatherhood may need to start changing how they use laptops, a U.S. reproductive specialist warns.

Dr. Suzanne Kavic of the Loyola University Chicago Stritch School of Medicine in Maywood, Ill., near Chicago, says excessive laptop use has been linked to male infertility.

"Laptops are becoming increasingly common among young men wired into to the latest technology," Kavic says in statement. "However, the heat generated from laptops can impact sperm production and development making it difficult to conceive down the road."

Kavic -- director of the division of reproductive endocrinology at the Loyola University Health Systems and an associate professor in the department of obstetrics and gynecology and department of medicine at the School of Medicine -- recommends placing laptops on desktops to prevent damaging sperm and decreasing counts and motility.

Sperm quality and quantity as well as sperm motility -- movement -- are key to male fertility, Kavic says.
